摘要:
A microphone having a microphone capsule (10) and a microphone capsule suspension (20) is provided. The microphone capsule suspension (20) has a first and a second housing section (10, 30) and also a decoupling unit (40). In this arrangement, the microphone capsule (10) is mounted on the decoupling unit (40) for the purpose of decoupling structure-borne sound. The decoupling unit (40) is in turn attached to the first and/or second housing section (10, 30). The decoupling unit (40) has a shape alteration section which alters the shape under load. The decoupling unit has at least two arms, each of which has a first and a second end. The respective second ends have an attachment section for holding a microphone capsule. Each arm has a shape alteration section, which alters the shape under a first load, and an elastic section, which allows elastic deformation of length from a second load onwards.

The invention relates to a headset comprising a first housing (LK, AK, IK) for receiving an electroacoustic converter and a second housing (RK, AK, IK) for receiving an electroacoustic sound transducer, at least one outer microphone (M1) for recording outside noise, and at least one inner microphone (M2) for recording sound in the region between an ear of the user and the first and/or second housings (LK, RK, AK, IK). The headset further comprises a digital active noise reduction unit (ANR) for performing active noise reduction based on the sound recorded by the at least one outer microphone and the at least one inner microphone. The active noise reduction unit (ANR) comprises an analysis unit (AU) for analyzing the sound recorded by the outer microphone and the inner microphone and for determining the signal types of the recorded sound. The active noise reduction unit further comprises a plurality of signal processing units (SVE1 - SVEn), which are each designed to perform active noise reduction for a signal type. The analysis unit (AU) selects at least one of the signal processing units (SVE1 - SVEn) for performing a noise reduction step based on the analysis that was performed of the recorded sound.
摘要:
The invention relates to a capacitor microphone comprising a microphone housing having a sound inlet and a membrane of a counter electrode associated with the membrane at a small distance from said membrane. The aim of the invention is to provide a capacitor microphone having extremely compact dimensions and a high signal-to-noise ratio without detracting from electroacoustic parameters. According to the invention, the microphone housing consists of two housing parts. The second housing part has a diameter which is larger than the first housing part and the second housing part is arranged on the first housing part in the form of a cap or sleeve and the edge of the membrane is folded back over the edge of the first housing part and fixed to the outside of the first housing part.

The invention relates to headphones for connection to an external active noise compensation device. Said headphones comprise at least one earphone, an ear proximal microphone and passive circuitry for increasing the amplification of the external noise compensation device. Noise compensation of the external noise compensation system can be increased by increasing the overall amplification by the passive circuitry.
